Notes: The monotypic genus Polycyclina is parasitic on living leaves of Lomaria imperalis (drawing see Thambugala et al. 2014b; Wijayawardene et al. 2018, 2020). Polycyclina is characterized by solitary, superficial, circular to elliptical to irregular, disc-like, black, rather flat ascostromata, clavate to cylindric-clavate asci and ellipsoid to cylindric-ellipsoid, dark brown, aseptate ascospores (Thambugala et al. 2014b).
